There are meme "speedrun any%" videos on YouTube for this sort of thing, so there are probably some real ones out there. FWIW I made a female character on FFXIV (partly to see if this sort of thing would happen) and never encountered this. Maybe I put out a male vibe with how I move and play (I heard we jump around a lot more). But in my experience that game's populace skews far more heavily female than normal, and a lot of the guys I met also play as female characters so maybe that's why.
